Hi,
you did not say, which version of WHS you are talking about. Windows Home Server is primarily a Backup appliance for client PCs. Additionally it offers sharing of files and media and Remote Access.
Only file and media sharing is possibe with Windows 10 in a similar manner, a backup facility for other clients does not exist, nor does Remote Access in such an easy way. Also keep in mind, that you would need a full version of Windows 10 (which costs money)
or install a unused license of Windows 7 or 8.1 first, activate it and update this.
Best greetings from Germany
